Abstract:

The eastern edge of the Ordos Basin is one of the most active areas in coalbed methane exploration and exploitation. Integrated with previous exploration data, the authors simulated sedimentary and thermal history of this area, and divided its thermal evolvement into 3 stages.Based on it, through analyses of gas-bearing property, penetrability and pressure gradient,it is drawn that the gas-bearing property is high in the south and west and is low in the north and east horizontally, and coal with good penetrability is mainly mid-metamorphic grade in this area. Finally, the target areas are indicated, and some rational suggestions are proposed.

Key words: the Ordos Basin, coalbed methane, resources, target
